Chinese online retailer JD.com took over internet giant Tencent’s e-commerce operations back in March, and now it has relaunched the latter’s Paipai eBay-like consumer-to-consumer marketplace, taking its battle with Alibaba up a notch.

The newly-refurbished platform has more emphasis on search relevance rather than advertising, boasts reduced marketing costs for sellers and lets users complete orders through JD’s nationwide fulfillment network — which means access to same-day and next-day delivery.

The search function is particularly important as it helps to keep users on the platform. JD is using a new algorithm on Paipai that prioritizes sellers based on factors such as buyer feedback, the variety of relevant products sold, amid other factors. Sellers will also be able to access JD’s last-mile logistics network and finance tools.

Tencent took a 15 percent stake in JD and subscribed to another 5 percent after JD completed its IPO in the US, which raised $1.78 billion. Now it looks like JD is gearing all up to compete with Alibaba, as it builds Paipai up into a serious competitor to compete with Alibaba’s Taobao marketplace. Tencent never really managed to see its e-commerce operations take off, so having JD as an ally makes sense, and could seriously threaten Alibaba.
